Specification of Letters Patent.

Application filed July 5, 1917. Serial No. 178,663.

To all whom it may concern:

Be it known that I, JACK SARA, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Power Plants; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to certain new and useful improvements in energy generating apparatus suitable for shop purposes and has primarily for its object to provide a device of this character which will generate electrical current and compress and store fluids at the same time for ordinary shop purposes such as chippers,'riveters and so on. v

A further object is to provide such a device having a suitable source of power driving an electrical generator and reciprocating a mobile cylinder and a piston operable in the cylinder for compressing fluids.

With the above and other objects in View which will appear as the description pro ceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles thereof, in which:

The single view is a top plan view of my complete energy generating apparatus with parts broken away and in section to more clearly illustrate structural details.

Referring now more particularly to. the accompanying drawings, resents the reservoir for su plying fluid to a cylinder 2 of the engine or operating my apparatus, which may be of any desired type such as steam or hydraulic.

This engine comprises in the present 1nstance a piston 3 mounted in the cylinder 2 for reciprocative movement and having its piston rod 4 pivoted in a yoke 5 of a connecting rod 5 having its outer end pivoted to the crank arm of a crank shaft 6. This crank shaft 6 is journaled in suitable bearable pipes the numeral 1 repings formed on a supporting base 7 and has mounted on its outer end a conventional fly wheel 8 and carries on its outwardly of said fly wheel a cam member 9 for operating a spring controlled valve rod 10 having its outer end pivoted to a crank lever 11 or operating an escapement valve 12- disposed in the supply pipe 1 leading from the reservoir 1 to the cylinders, suit 13 connecting the escapement valve with ports disposed near the ends of the cylinder 2. This escapement valve is of conventional design having usual partitlons 12 for simultaneously connecting one of the pipes 13 with the supply pipe 1 and the other pipe 13 with an exhaust opening 13.

A sprocket wheel 14: is mounted on the end of the crank shaft 6 opposite its fly wheel 8, and is connected by a sprocket chain 16 with a sprocket wheel 14: on one end of a.crank shaft 15. The crank shaft 15 is journaled 1n bearings 17 formed on a base or supporting structure 18 and has its end opposite fiy wheel 15' coupled with an electrical energy generator 19 of any desired type or construction. Thus it will beseen that when the valve 2 in the supplypipe 1 is open in order to cause the operation of the driving engine, the crank shaft 15 will be revolved thereby to operate the generator 19 to create electrical energy, as will be obvious.

The crank shaft 15 has one end 20 of a connecting rod 21 journaled in its crank arm, the other end of said rod being connected universal joint 23 and, as will be apparent, upon the rotation of crank shaft 15, the cylportion projecting with a mobile cylinder 22 by means of a inder 22 will be reciprocated; spiral or other suitable springs 24: being mounted upon the end wall ofshaft 15 for engaging stops 24', formed on bearings 17, when the cylinder reaches its limit ofmovement toward said crank shaft.

The cylinder 22 is mounted upon any suitable support (not shown) and has near each end thereof an outlet 25 from each of which leads an elbow 26 slidably receiving in its inner end the inner end of an elbow 26 having its outer end connected with a manifold 27' communicating with a storage tank 28 by means of pipe connections 29. Intake check valves 25' are provided at the ends of the cylinder 22.

The manifold 27 is preferably disposed either aboveor below the horizontal plane of the cylinder 22 and in order to permit the resaid cylinder adjacent crank ciprocative movement of said cylinder, the elbows 26 and 26 have their outer ends pivotally connected with the manifold 27 and the outlets 25 by means of suitable swivel air tight joints 30 and have their inner ends telescoping. A gate valve 27 is disposed in each arm of the manifold near the outer ends thereof to prevent the fluid in the storage tank from flowingback into the cylinder 22.

A piston 31 is mounted in the cylinder 22 and has its rod 32 double threaded for engagement with the internally threaded bar 33 of a sleeve 34 journaled in a bearing 35 formed on the supporting base 36. Formed on one end of said sleeve is a beveled gear g which, through means 37 in mesh with a beveled gear 38 disposed at right angles thereto and fixed upon a shaft 39 journaled in a bearing 40 also formed on the base 36. This shaft 39 carries on its end opposite gear 38 a pinion gear 41 meshing with a rack bar 42 slidably mounted in bearings 43. and reciprocated by means of a connecting arm a l having its outer end secured to the yoke 5 of the connecting rod 5.

Thus it will be seen that the piston 3 in its reciprocative movement carries with it the rack bar 42 which rotates the pinion gear 41, and with it the beveled gears 38 and 37 in one direction and then in a reverse direction,

of sleeve 34, reciprocates the piston 31. The cylinder 22 is moved forwardly through the medium of connecting rod 21, pivoted to crank shaft 15 at the same time the piston 31 is moved for I wardly, the average speed of reciprocation of said cylinder being approximately one half of that of the piston 31.

By reciprocating the piston 31 at a speed greater than that of cylinder 22, the compressing of fluids in said cylinderis accom plished, as the piston will have reached the opposite end of the cylinder by the time the same has reached its extreme forward limit of movement, and vice versa.

From the foregoing description taken in connection with the drawings the operation of my apparatus will be'obvious and it will be understood that if desired any suitable operating engine may be utilized and that in place of the generator 19 any other form of apparatus may be used. I The essential .feature of my invention is an arrangement for economically compressing air incidental to the driving of a mechanism by a main source of power operable by a reciprocating action.

The compression cylinder 22 and associated mechanism serve the single function of a pump, and by arranging the mechanism in the general manner shown, I utilize the reciprocative force of the primary piston plunger 4 in a pump action immediately at the time when the crank of the engine shaft is working at a most disadvantageous leverage, that is, at and adjacent dead center.

I claim.

1. An apparatus of the class described including a work connected crank shaft, a reciprocating compression cylinder, a pitman connection between said cylinder and the crank shaft, a piston reciprocable in the compression cylinder, a stem for the piston, and a prime source of power connected with the stem for reciprocating it.

2. An apparatus of the class described including a work connected crank shaft, a reciprocating compression cylinder, a pitman connection between said cylinder and the crank shaft, a piston reciprocable in the compression cylinder, a stem for the piston, a primary drive shaft connected with the stem for reciprocating it, and a sprocket chain connection between the primary drive shaft and the work connected shaft.

3. An apparatus of the class described including a work connected crank shaft, a reciprocating compression cylinder, a pitman connection between said cylinder and the crank shaft, a valve controlled conduit extending from each end of the compression cylinder, a piston reciprocable in the compression cylinder, a stem for the piston, and a prime source of power connected with the stem for reciprocating it.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin.

JACK SARA.
